"lexical morpheme"的定义和意义

What is a "lexical morpheme"?

A lexical morpheme is a type of morpheme that carries specific meaning and contributes to the content of a word. These morphemes typically consist of root words or stems that refer to objects, actions, or concepts. For example, in the word "dogs", the lexical morpheme is "dog", which refers to the animal, while the "s" indicates the plural form. Lexical morphemes are essential for conveying the main ideas in communication, as they provide the foundational meanings upon which additional grammatical information can be added through other types of morphemes, such as inflectional or derivational morphemes.
